Answer:

19 i think

Step-by-step explanation:

the problem describes an isosceles triangle by saying that two sides are congruent

You can also infer that <T is the vertex so subtract that from 180 to find what the combined two missing angles are

you get 38, now divide that by 2 to find the missing angle

What is a cube in math
DerKrebs [107]

Answer:

In arithmetic and algebra, the cube of a number n is its third power, that is, the result of multiplying three instances of n together. The cube is also the number multiplied by its square: n3 = n × n2 = n × n × n.

What is the value of x?
andrey2020 [161]

Answer:

x = 30°.

Step-by-step explanation:

To calculate the value of 'x', we can first derive the value of one of the angles that make up the triangle.

Notice that there is an angle with a measure of 100°. The angle that makes up the angle of the triangle is called a Vertical Angle. Therefore, if the angle in red is 100°, the vertical angle, or the third angle of the triangle, is 100°.

There are two congruent sides to the triangle, as seen by the congruent lines. This means that both of the other two angles must be equal. Find the value of 'x' by:

180 - 100 = 80. Since the value of one angle was 100°, and the angles in a triangle must add up to 180°, you can simply subtract to find the sum of the other two angles.

(x + 10) + (x + 10) = 80

2x + 20 = 80

2x = 60

x = 30°.

Quick algebra 1 assignment for 50 points!
Sergeeva-Olga [200]

The example on direct variation is illustrated below based on the information given.

<h3>How to illustrate the direct variation?</h3>

An example will be:

When x = 2, y = 10. Find the value of y when x is 6.

In this case, this will be calculated thus:

y = kx

10 = 2k

k = 10/2

k = 5

Since y = kx.

y = 5 × 6

y = 30

The value of y is 30.

Susan drove to visit a friend. She drove 345
padilas [110]

Answer:

Average\ Speed = 60 mi/hr

Step-by-step explanation:

Given

Distance = 345\ miles

Time = 5\ hours\ 45\ minutes

Required

Determine the average speed

This is calculated as thus:

Average\ Speed = \frac{Distance}{Time}

Convert time to hour:

Time = 5\ hours\ 45\ minutes

Time = 5\ hours + \frac{45}{60}\ hour

Time = 5\ hours + \frac{3}{4}\ hour

Time = \frac{20 + 3}{4}\ hours

Time = \frac{23}{4}\ hours

Time = 5.75\ hours

Average\ Speed = \frac{Distance}{Time}

Average\ Speed = \frac{345}{5.75}

Average\ Speed = 60 mi/hr

Brainly to whomever somehow solves for x. I WILL REPORT SCAMS AND UNHELPFUL "WHAT?" ANSWERS.
cestrela7 [59]

Answer:

x=\frac{33}{7}

Step-by-step explanation:

Since ED is parallel to CA, the two triangles in the figure share all 3 angles and therefore must be similar. By definition, the corresponding sides of similar polygons are in a constant proportion.

Therefore, we have:

\frac{11}{11+x}=\frac{14}{20},\\14(11+x)=20\cdot 11,\\11+x=\frac{20\cdot 11}{14},\\x=\frac{110}{7}-11=\boxed{\frac{33}{7}}
